For example, on WhatsApp, use the whole 25 character limit for profile name. Examples:

Bob Moved To Signal.org

Alice MovedTo Signal.org

CharlieMovedTo Signal.org

Say Signal.org, not Signal, because they won’t know it’s an app.

Use your about section too. Same on Discord, Steam, Instagram, etc.

    Signal is designed to collect meta-metadata. They don’t hold any information that can tie a person to their account, but they definitely know how those accounts interact via their servers.

        How do they know your phone number? Only a cryptographic hash of it is sent to their servers.

          Not really. See the support page regarding this:

          As a new default, your phone number will no longer be visible to everyone in Signal. You can opt to display your phone number. However, people who have your number saved in their phone’s contacts will still see your phone number, regardless of your settings, since they already know it.
